Dr Julie Mudd from Townsville's Public Health Unit confirmed another 10 people were being treated for melioidosis.

"As of today, there has been a further two confirmed cases of melioidoses taking the number of cases to 10 and sadly we've also had one death," she told 9News yesterday.

"Given the scale of the flooding we are expecting to see increasing numbers of a range of infections, not just melioidosis, and we are proactively testing for these illnesses.

"Melioidosis and many infections that stem from flooding can more severely impact people who are unwell or elderly or have existing chronic conditions."

The Health Unit is now urging those in flood-affected areas to check on their neighbours and check in on the elderly. If they are unwell or have a fever, they want residents to call a doctor or an ambulance immediately.

"Floodwater is heavily contaminated with dirt and bacteria," a statement said.

"The vital public health message has been to ensure flood water doesn't get into your body through cuts and scratches."

The putrefying carcasses of cattle, sheep and wildlife that died in Queensland's once-in-a-century monsoonal deluge are also posing a health risk to clean-up crews and to local water supplies in flooded communities.
